A comparative study of physiological shifts in people when changing their residence showed that the adaptation to mountain as well as desert conditions proceeds in northerners at a slower rate than in southerners. Indices of the cardiovascular system, external respiration and their restoration period after physical stress are fairly analogous for southerners and permanent residents in mountain and desert localities, while for northerners different data had been noted. A relation between the adrenal cortex activity and temperature conditions was detected expressed by decreased activity of 17-ketosteroids due to high external temperature. In adaptation to mountain as well as to desert conditions southerners show higher reserve potentialities. It appeared that in southerners the adaptation process is faster and easier as compared with northerners nevertheless common features of physiological mechanism of adaption to external effects had been established.
